FileHippo link worked for me, but then Chrome was still unable to download/install any updates. I ended up uninstalling all Google software, deleting all Google folders, and deleting all Google entries from the registry (just deleting ImageState wasn’t enough). Now I can install all Google packages, including all flavors of Chrome and all updates! Whoo!

I fixed this issue by going into regedit and removing HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432\Node\Google\Chrome
and
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432\Node\Google\Update
Once those values were removed I was able to install Chrome, Google Earth, and updates.

I also had to delete the registry entries mentioned by Jaimy D. After removing them, both the filehippo and current installers worked fine. In this case the machine was a lenovo t430s with factory default chrome installation and windows 7 64bit
